Wet and Dry Bulb Hygrometer -10°C to 50°C Camon 3201
Wet and Dry Bulb Hygrometer (50°C) Data Sheet
1. Product Overview:
- Type: Wet and Dry Bulb Hygrometer
- Measurement Range: 0°C to 50°C
- Purpose: Measures relative humidity using the temperature difference between the dry bulb (air temperature) and the wet bulb (evaporation-cooled temperature).
2. Key Features:
- Temperature Range: -10°C to 50°C
- Humidity Range: 0% to 100% RH (Relative Humidity)
- Accuracy: ±5% RH
- Material: Plastic casing with dual thermometers
- Scale: Celsius (°C)
3. Components:
- Dry Bulb: Measures the ambient air temperature.
- Wet Bulb: Measures the cooled air temperature due to water evaporation.
- Evaporation Wick: Soaked in water, wrapped around the wet bulb for cooling by evaporation.
4. Operation Instructions:
- Mounting: The hygrometer should be placed in a shaded, ventilated area to avoid direct sunlight, which can affect readings.
- Reading:
- Observe the dry bulb temperature.
- Observe the wet bulb temperature.
- Determine the temperature difference.
- Use the provided chart to determine relative humidity.
5. Relative Humidity Calculation Table:
(Example table below is based on a general understanding of how wet and dry bulb temperature differences are calculated for relative humidity)
| Dry Bulb (°C) | Wet Bulb Depression (°C) | Relative Humidity (%) |
|---|---|---|
| 30 | 2 | 85 |
| 30 | 5 | 70 |
| 30 | 8 | 50 |
| 40 | 2 | 90 |
| 40 | 5 | 75 |
| 40 | 8 | 60 |
| 50 | 2 | 95 |
| 50 | 5 | 80 |
| 50 | 8 | 65 |
Note: You can refer to the central chart between the thermometers for exact readings of humidity for each temperature difference.
6. Maintenance:
- Cleaning: Clean the thermometers and the wick regularly for accurate readings.
- Water Supply: Ensure the wick around the wet bulb is kept moist by maintaining a supply of distilled water.
7. Applications:
- Used in weather stations, greenhouses, laboratories, and other environments where relative humidity and temperature control are critical.
